Never mind, that savestate doesn't load for some reason. Want to take a break from this now, but to get this out of the way:
D19F is item 1 ID; set it to 01 for Master Balls. Then set D1A0 to FF for 255 of them. Set D19F (or D1A1) to 20 for Rare Candies, then D1A0 (or D1A2) to FF for 255 of them. I've attached a cheat list with these. Hope this helps!
